Hi,

Since you have given your improvement exams and successfully scored 65% in PCB, then you can go ahead and fill the NEET examination form using your roll no. of improvement exam only. The only academic requirement they ask for is a score of 50%+ in 12th examinations. You can use the improvement marksheet for the procedure.

Keep in mind that you will need to present the same mark sheet for all future purposes and at the time of counselling, so make sure you save it as well.
